JOAOHIM STEIN, OF NEW YORK, N.Y.

SPECIFICATION forming part of Letters Patent No. 261,270, dated Ju1y 18, 1882.

Application filed May 20, 1882.

To all whom it may concern:

Be it known that I, JOACHIM STEIN, a citizen ot'Bohemia, Austria, residing at New York, in the county and State of New York, have in- 5 vented a new and useful Process for Bleaching Hair, of which the 'following is a complete, full, and exact specification.

My invention relates to an improved processfor bleaching first-class human hair in such a in manner that the resultant color shall be white steps.

I, jydrogei which is mixed well with onegixteef ffli part of ammoniajdfter this solution is'iiiarle the next step is to take one-qt arter of a pound of th peroxide of hydrogenand mix it with one ounce of th "cream of tartar dissolvediin one ounce of soda This forms the second solution. These tw solutions are then mixed, and the hair is thoroughly saturated with the mixture and allowed to remain in it three hours. Then the hair is removed and washed in clean water with what is commonly known as soapine, in a hath made of pottery or clay. When the hair is thoroughly dried,

this process is repeated for fifteen or sixteen (N0 specimens.)

times, but after the twelfth process, and with each succeeding process thereafter, the hair must be thoroughly mixed and shaken up. When the hair has been subjected to this process for sixteen times it is then drawn through 5 a solution of blue aniline and alcohol.

By means of this process and these mixtures the hair is made white instead ot'ye1low.- The addition of cream of tartar preserves the natural softness of the hair and prevents it from 0 becoming stiff or from breaking.

What I claim, and desire to secure by Letters Patent, is-

1. The herein-described process of bleaching hair, which consists, first, in saturating it with 5.

a mixture composed of two solutions, one of peroxide of hydrogen and ammonia and the other of peroxide of hydrogen and cream of tartar, in the proportions indicated, and then in passingit through a solution of blue aniline and alcohol,in the manner and for the purposes described.

2. The composition consisting of peroxide of hydrogen and cream of tartar, as and for the purposes described.

JOAUHIM STEIN.
